Welcome back, explorer! Today, we focus on a notorious code villain: Logical Errors. Unlike syntax errors from past lessons, logical errors whisper confusion into our program without halting it. They're often unnoticed, but when spotted, we can tackle them! So, let's dive in!

Logical errors pop up when our code deviates from our intended plan. There's no crashing of the program or error messages, which sounds fine, right? But hold on, they cause our output to diverge from what we anticipate.

Can you spot the logical error in the following piece of code?

Have you got it? Great! We wanted to add the numbers, but a multiplication operator slipped in by mistake. Such small mistakes can lead to logical errors, rendering incorrect output.

Finding logical errors might feel like locating a needle in a haystack. But worry not; we have some strategies. A useful method we employ involves using console.log() statements to print variable values during program execution. These checkpoints help us identify whether everything is running well.

The unexpected discrepancy between "Expected sum" and "Actual sum" helps flag the logical error.

Let's look at some common logical errors.
